Yeah, this bug it´s fixed for the new version. Meanwhile, you can fix it by replacing the CI_Input::_html_entity_decode_callback method with this code
Code:
function _html_entity_decode_callback($match)
{
global $CFG;
$charset = $CFG->item('charset');
return $this->_html_entity_decode($match[0], strtoupper($charset));
}
